All time zones defined by difference with UTC Min. At different times in the past, it has been calculated in different ways, including being calculated from noon; [1] as a consequence, it cannot be used to specify a precise time unless a context is given.

The term GMT should not thus be used for technical purposes. This event may occur up to 16 minutes before or after noon GMT, a discrepancy calculated by the equation of time.

Noon GMT is the annual average i. Originally, astronomers considered a GMT day to start at noon, while for almost everyone else it started at midnight.

As the United Kingdom grew into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was by convention considered to have longitude zero degrees, adopted in the International Meridian Conference of Synchronisation of the chronometer on GMT did not affect shipboard time, which was still solar time.

Greenwich Mean Time was adopted across the island of Great Britain by the Railway Clearing House in and by almost all railway companies by the following year, from which the term " railway time " is derived.

It was gradually adopted for other purposes, but a legal case in held " local mean time " to be the official time. For example, our polling booths were opened, say, at 8 13 and closed at 4 13 p.

On 1 January , GMT was superseded as the international civil time standard by Coordinated Universal Time, maintained by an ensemble of atomic clocks around the world.

Universal Time UT , a term introduced in , initially represented mean time at Greenwich determined in the traditional way to accord with the originally defined universal day ; from 1 January as decided by the International Astronomical Union at Dublin in , at the initiative of William Markowitz this "raw" form of UT was re-labelled UT0 and effectively superseded by refined forms UT1 UT0 equalised for the effects of polar wandering [10] and UT2 UT1 further equalised for annual seasonal variations in earth rotation rate.

Indeed, even the Greenwich meridian itself is not quite what it used to be—defined by "the centre of the transit instrument at the Observatory at Greenwich".

Historically, GMT has been used with two different conventions for numbering hours. The long-standing astronomical convention dating from the work of Ptolemy , was to refer to noon as zero hours see Julian day.

This contrasted with the civil convention of referring to midnight as zero hours dating from the Roman Empire. The latter convention was adopted on and after 1 January for astronomical purposes, resulting in a discontinuity of 12 hours, or half a day.

The instant that was designated "December The Interpretation Act , section 9, provides that whenever an expression of time occurs in an Act, the time referred to shall unless otherwise specifically stated be held to be Greenwich mean time.

Under subsection 23 3 , the same rule applies to deeds and other instruments. Several countries define their local time by reference to Greenwich Mean Time.

Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines.

Most of European Russia , including Moscow , St. As this time zone is predominantly in the equatorial region, there is no significant change in day length throughout the year, so daylight saving time is not observed.

Arabia Standard Time is used by the following countries: Kiev , Bucharest , Jerusalem , Athens. This proved unpopular because of the dark mornings, children walking to school and people going to work in complete darkness.
